The Linksys WRT54G Wi-Fi series is a series of Wi-Fi–capable residential gateways marketed by Linksys, a subsidiary of Cisco from 2003 until acquired by Belkin in 2013. A residential gateway connects a local area network (such as a home network) to a wide area network (such as the Internet).
Hardware and revisions
The original WRT54G was first released in December 2002. It has a 4+1 port network switch (the Internet/WAN port is part of the same internal network switch, but on a different VLAN). The devices have two removable antennas connected through Reverse Polarity TNC connectors. The WRT54GC router is an exception and has an internal antenna with optional external antenna.
As a cost-cutting measure, the design of the latest version of the WRT54G no longer has detachable antennas or TNC connectors. Instead, version 8 routers simply route thin wires into antenna 'shells' eliminating the connector. As a result, Linksys HGA7T and similar external antennas are no longer compatible with this model.

Linksys WRT54GS version 7.2
The WRT54GS is nearly identical to the WRT54G except for additional RAM, flash memory, and SpeedBooster software. Versions 1 to 3 of this router have 8 MB of flash memory. Since most third parties' firmware only use up to 4 MB flash, a JFFS2-based read/write filesystem can be created and used on the remaining 4 MB free flash. This allows for greater flexibility of configurations and scripting, enabling this small router to both load-balance multiple ADSL lines (multi-homed) or to be run as a hardware layer-2 load balancer (with appropriate third party firmware).

Close-up of the circuit board
Linksys released the WRT54GL (the best-selling router of all time) in 2005 to support third-party firmware based on Linux, after the original WRT54G line was switched from Linux to VxWorks, starting with version 5. The WRT54GL is technically a reissue of the version 4 WRT54G. Cisco was sued by the FSF for copyright infringement, but the case was settled.
|1.0||Broadcom BCM5352 @ 200 MHz||16 MB||4 MB||CL7A||New model line, released after the version 5 WRT54G, which returns to a Linux-based OS as opposed to the VxWorks firmware. SpeedBooster is not enabled in stock firmware, however third-party firmware will enable the feature. The hardware is essentially the same as the WRT54G version 4.0. One alteration is that the internal numbering scheme of the 4-port switch changed in this model, from 1 2 3 4, to 3 2 1 0.|
|1.1||Broadcom BCM5352 @ 200 MHz||16 MB||4 MB||CL7B CL7C CF7C||Detachable antennas. As of August, 2009, this version was shipping with firmware revision 4.30.11. This pre-loaded firmware allows the user to upload a 4 MB firmware image, whereas the pre-loaded firmware on version 1.0 limited the image to 3 MB. Firmware version 4.30.18 is now available for both hardware versions. Fully supported by Tomato, OpenWrt, and DD-WRT.|
WRTSL54GS is similar to the WRT54GS while adding additional firmware features and a USB 2.0 port (referred to as StorageLink) which can be used for a USB hard disk or flash drive.
Unlike other models, the WRTSL54GS has only a single 1.5 dBi antenna, and it is not removable.

The Linksys WTR54GS is a confusingly named derivative of the WRT54G. It is a compact wireless travel router with SpeedBooster support that has only one LAN and one WAN Fast Ethernet interfaces, but has two wireless interfaces. The WTR54GS has the ability to make an unencrypted wireless connection on one interface, and make open shared connections on the other wireless interface, or the LAN port.

LinkSys WRT54GC V2.0 Compact Wireless-G Broadband Router.
WRT54GC series with 802.11b/g support. This unit has a four port 10/100 switch and one WAN port. The "C" in the router number stands for compact, as the unit measures 4" by 4" by 1" with an internal antenna. The unit can be expanded with addition of HGA7S external antenna to boost range. Hardware Version 1.0 is the only option available in the United States since introduction in 2005.
Version 2.0 is shipping in, amongst other countries, the United Kingdom. This unit has 1 MB flash, 4 MB RAM and a non-detachable external antenna.
The internal hardware is based on a Marvell ARM914 ("Libertas") reference design which is probably identical to the SerComm IP806SM, Xterasys XR-2407G, Abocom ARM914, Hawking HWGR54 Revision M, and the Airlink 101 AR315W. By appropriately changing the value of the firmware byte 0x26, the WRT54GC can be cross-flashed with firmware based on the same reference platform.
There were reports in 2006 that a sister platform of the WRT54GC (the AR315W) was hacked to run Linux.
WRT54G3G/WRT54G3GV2 Mobile Broadband router
A variant which has four Fast Ethernet ports, one Internet wired port (For DSL/Cable connections), plus a PCMCIA slot for use with a Cellular Based PC Card "aircard". The V2 model has an additional 2 USB ports for 3G modem use and 1 other USB port which has yet to be put to use.
|WRT54G3G||A Vodafone branded unit that comes with programmed settings for the Vodafone network supporting GPRS, UMTS and HSDPA. It can only accept the 3G PCMCIA cards and ExpressCards sold by Vodafone. It has no USB port to accept 3G USB dongles. The router can be use in other networks if the 3G cards are unlocked, because it is not the router, but the 3G cards that are locked to Vodafone. To use it in other networks it is necessary to change the settings of the APN, User and Password manually to those of the new network. It can also be unlocked by flashing EM/EU version firmware. With the latest firmware upgrade it supports full HSDPA up to 7.2 Mbit/s. Some of 3G cards that it supports, like the Huawei E800/E870 and the Option GT Fusion, have external Antenna port to improve the reception of the 3G signals. It works with the PCMCIA Globetrotter card too.||Fully Supported by OpenWRT|
|WRT54G3G-ST||A Sprint Wireless (USA) unit which supports CDMA 1X and EVDO rev 0,A wireless Internet.||Fully Supported by OpenWRT|

|WRT54G3G-EU||European Union version supporting GPRS, UMTS and HSDPA.||Fully Supported by OpenWRT|
|WRT54G3GV2-VF||A Vodafone branded unit which supports full HSDPA up to 7.2 Mbit/s and seems not to be locked to the Vodafone network (Via setting APN, User and Password manually) but does not work with all USB dongles (T-Mobile: Web'N-Walk-Stick III (Huawei 172) and IV (Huawei 176 – has ext. Antenna port) are well supported, out of the box. Huawei E220 is also supported – firmware upgrade maybe needed).||Partial Supported by customization of Linksys GPL code and supported by OpenWRT. NOTE: Due to changes in the CFE (bootloader) it is not fully supported yet. You should not try it without a serial console.|
Other Cellular Providers
To use this router with other cellular providers, one must use an Alternative Firmware provider. The Stock Firmware does not support cellular providers, even though one does have the exact supported aircard. e.g.: Telus Mobility (CANADA) uses the Sierra Wireless Aircard 595 which is supported by this router, but because it is from Telus Mobility and not from Sprint (USA), it will never load the card into the router to make it operational. This is only true for the Sprint and AT&T branded models.
WRT54G-TM, WRTU54G-TM, and WRTU54GV2-TM
The WRT54G-TM (TM stands for T-Mobile) is also called the T-Mobile "[email protected]" service. It allows calls to be made via T-Mobile's GSM network or via Wi-Fi Unlicensed Mobile Access (UMA), using the same telephone and phone number (a special dual-mode phone designed for the service is required e.g. Blackberry Pearl 8120). Additionally, once a call is in progress, one may transition from Wi-Fi to GSM (and vice versa) seamlessly, as Wi-Fi signal comes and goes, such as when entering or exiting a home or business. A special router is not needed to use the service, but the T-Mobile branded routers are supposed to enhance the telephone's battery life. This is the only known tweak to the TM version of the firmware. The hardware appears similar to that of the WRT54GL, except it has 32 MB RAM and 8 MB flash memory.
The WRT54G-TM having a serial number that starts with C061 has these specifications:
- Broadcom BCM5352EKPBG CPU
- 32 MB RAM (Hynix HY5DU561622ETP-D43)
- 8 MB Flash (JS28f640)
- Uses the same BINs that the WRT54GS v3.0 does
|Broadcom BCM5352 @ 200 MHz||32 MB||8 MB||CO61||T-Mobile Edition WRT54GS V3.0 (Renamed WRT54G-TM). It is possible to upgrade to third-party firmware via JTAG or by replacing the CFS and uploading a new firmware over TFTP. Instructions for the CFS/TFTP method can be found easily on the Internet, and other third-party firmware can be easily applied afterwards.
The Tomato Firmware also works on the WRT54G-TM.
|Infineon ADM8668 @ 200 MHz||64 MB||8 MB||QMF00H||T-Mobile Edition Model: WRTU54G-TM. This version has two RJ-11 telephone ports and two SIM card slots. The WRTU54G-TM is not supported by DD-WRT. It can be flashed, and work is being done to port OpenWRT to this board|
|T-Mobile Edition Model: WRTU54GV2-TM. This version has two RJ-11 telephone ports and two SIM card slots it is black like the UTA-200-TM. However unlike the UTA-200-TM has four Fast Ethernet ports instead of a single pass-through Ethernet port.|
|See also: UTA-200|
The WRT54G-RG (RG stands for Rogers) is also called the Rogers TalkSpot Voice-Optimized Router. It works with Rogers' Talkspot UMA service, which allows calls to be made via Rogers' cellular network or via Wi-Fi Unlicensed Mobile Access (UMA), using the same telephone and phone number. A UMA-compatible phone is required. The WRT54G-RG and the WRT54G-TM are identical in terms of hardware.
|WRT54G-RG||Broadcom BCM5352 @ 200 MHz||32 MB||8 MB||CDF1||FCC ID: Q87-WT54GV40. The WRT54G-RG is supported by DD-WRT.|
The WRT54GH comes with an internal antenna, a four-port network switch, and support for Wi-Fi 802.11b/g.
Third-party firmware projects
After Linksys was obliged to release source code of the WRT54G's firmware under terms of the GNU General Public License, there have been many third party projects enhancing that code as well as some entirely new projects using the hardware in these devices. Three of the most widely used are DD-WRT, Tomato and OpenWrt.
Hardware versions and firmware compatibility
As of January 2006, most third-party firmware is no longer compatible with version 5 of both the WRT54G and the WRT54GS. The amount of flash memory in the version 5 devices has been reduced to 2 MB, too small for current Linux-based third-party firmware. (See table above for information on identifying the version based on the serial number printed on the bottom of the unit, and on the outside of the shrink-wrapped retail box.)
Some users have succeeded in flashing and running a stripped down but fully functional version of DD-WRT called 'micro' on a version 5 WRT54G. An easier method not requiring any disassembly of the device has since been devised for flashing v5-v8 to DD-WRT.
To support third-party firmware, Linksys has re-released the WRT54G v4, under the new model name WRT54GL (the 'L' in this name allegedly stands for 'Linux'). It is also possible to replace the 2 MB flash chip in the WRT54G with a 4 MB flash chip. The Macronix International 29LV320BTC-90 is a suitable part although others may work as well. The user must first install a JTAG header and use a JTAG cable to back up the firmware, then replace the chip and restore the firmware with the JTAG cable. After testing for proper functionality of the modified unit, third-party firmware can be flashed using the JTAG cable and a suitable image file.
With the Attitude Adjustment (12.09) release of OpenWrt, all WRT54G hardware versions with 16 MB of RAM are no longer supported, and older Backfire (10.03) is recommended instead. Issues came from dropping support for the legacy Broadcom target
brcm-2.4, making lower end devices run out of memory easily. Support for Attitude Adjustment is limited to WRT54G hardware versions with 32 MB of RAM, what includes WRT54GS and (apart from performing RAM upgrades through hardware modifications) some of the WRT54G and WRT54GL versions having the capability for unlocking their additional 16 MB of RAM.
